Effects of single-walled carbon nanotube defects and alignment angles on percolation conductivity in carbon nanotubes thin film

thin film carbon nanotubes have shown interesting potential for practical application such as sensors and transparent conductive films. However, lack of theoreticalbackground on thin films and their dependency on CNTs properties prevent the progression of the technology in electronic. In this paper, based on the Monte-Carlo approach, we study the effects of nanotubes orientations and double vacancy on the percolation conductivity. We show that defects can decrease the film conductance. However, CNTs which are highly orientated will increase the conduction, significantly.CNTs alignment in specific direction may cause the film to reach the percolation threshold at higher values. Furthermore, we represent that, these values vary for different angles andorientations. These results can be implemented in practice, in order to provide the optimal conductance for single-walled carbon nanotube films.
